How to remove a preset?
On Mac you can access and manage presets from
Finder
Go (upper menu) hold Alt key to bring Library on the list
Library &gt; Application Support &gt; Blender &gt; 2.93 &gt; scripts &gt; presets
or
Go to Folder shift+cmd+G
and paste this path directory
~/Library/Application Support/Blender/2.93/scripts/presets/

Terminal
cd ~/Library/Application\ Support/Blender/2.93/scripts/presets/


Notes: In all cases change the number 2.93 to your current Blender version you use. Specifically Sapling's presets are stored in sub folder operator &gt; add_curve_sapling. Difference in path for Finder and Terminal is just in representation of space character in name of Application Support - Terminal use back slash and space.
